.SHEARS.

SPECIFICATION forming part of Letters Patent no. 598,195, dated April22, 1902.

Application filed July 8, 1901- Renewed March 18, 1902. berial No.98,721. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM GUY HEN- DERSON, a citizen of the UnitedStates, residing at Titusviile, in the county of Crawford,

State of Pennsylvania, have invented certain new and useful Improvementsin Shears, of which the following is a specification, reference beinghad therein to the accompanying drawings.

[0 This invention relates to shears, and particularly to a structure bywhich handles and blades are adapted to be separately formed andremovably attached.

The invention has for its object to produce animproved construction ofhandle and blade by which the two parts may be connected-together andheld by a single fastening device,

while the strain upon the blade will be borne upon an extension from thehandle and the use of blades of different lengths with the same size ofhandle permitted.

A further object of the invention is to provide for the use of differentcharacters of material in the handle and blade and to so combine theparts that the direct strain in the cutting action will not be entirelyborne by either the handle or the blade.

Other objects and advantages of the invention will hereinafter appear inthe following description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is an elevation of a pair of shears embodyingmy invention.

Figs. 2 and 3 are detail perspectives of the handle and blade of onemember of the shears, and Fig. 4 is avertical section on the line 4 4 ofFig. 3. I

Like letters of reference indicate like parts throughout the severalfigures of the drawings.

The invention has been shown as applied to shears; but it is quite,capable of application to scissors or any other character of cuttingdevice in whichit may be desirable to construct the blade of steelor'other preferred material for a cutting device, while the handle maybe made of a cheaper or different material, such as cast metal.

The shears are, as usual, composed of two .bined with a stock-handle,thus materially a bolt D or other securing device common in the art. Thehandle 0, as shown in Fig. 2, is provided with the pivoting-plate (3,having thereon a shoulder 0 against which the op- I posite member of theshears abuts when the same are in a closed position. The plate 0' isprovided with an aperture 0 adapted to receive the bolt D, and withanextension 0 adapted to lie within a recess B, formed within the blade B.This extension may be beveled or dovetailed, as shown, and the recess Bof a similar shape to receive the same and prevent any lateral movementof the parts upon each other. The blade Bis further provided at itspivoting end with a lug B having therein an aperture B said lug beingoffset from the cutting-face'of the shearsto provide a shoulder Badapted to abut against the I shoulder C of the handle when thebolt-apertures B and C are in alinement, the lug B lying upon the outerface of the handle. The

opposite member of the shears is of substan- 8o tially similarconstruction,and when the parts are combined a flush and smoothcutting-face between the blades is provided.

It will be seen that. the structure herewith presented permits the useof a single handle 8 5 casting of one size with any desired length ofblade, the construction of parts being so simple that the blades formedof different lengths and characters can readily be comeconomizing in themanufacture of shears and similar tools. I

A further important feature of construction is the manner of connectingthe handle and blade by which the cutting strain through 9 5 toughmaterial is relieved or removed from a single point and applied upon anextended bearing formed by the tongue or extension 0 resting in therecess in the blade, and

this extension prevents all movement of the blade upon the handle whenthe parts are assembled and held by the single securingbolt, whichprevents any longitudinal movement of the blade upon the extension fromthe handle, While the beveled or dovetailed construction retains theparts againstlateral movement.

It will be obvious that changes may be made in the details ofconstruction or configuration of either the blade or the handle withoutdeparting from the spirit of the invention as defined by the appendedclaims.

Having described my invention, what I claim is- 1. A shears comprising acutting member having a handle provided with a pivotingplate and anextension beyond the pivot in the plane of said plate, ablade providedwith a recess parallel with the edge thereof to receive said extensionand a pivoting ear adapted to lie upon the outer face of said plate, anda pivot passing through said ear and plate; substantially as specified.

2. A shears comprising opposite cutting members each having a handleportion provided with a pivoting-plate and a beveled extension in theplane thereof, a cuttingblade for each member provided with an undercutrecess to receive said extension and a pivoting-ear to lie upon theouter face of said plate, and a pivoting device passing through the earsand plates of both members of the shears to hold the blades againstlongitudinal movement and to clamp the members of the shears intocontact with each other; substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM GUY HENDERSON.
